* Fix Create PR preparation with unavailable lookup
* test(source-control): align dirty+unavailable intent expectation
Create PR preparation is allowed when review lookup is unavailable; only final create stays fail-closed. Update the local-blocker snapshot test to match.
* Keep Create PR intent running when hosted review lookup fails
A failed or timed-out hosted-review eligibility lookup no longer aborts
Create PR intent mid-run. Local prep (stage/commit/push) continues, the
branch-ahead refresh is deferred until after eligibility resolves, and the
final create preflight still fails closed to prevent duplicate reviews.
Also gate generated PR title/body on eligibility and thread the provider
through the intent run token so an unavailable lookup falls back to the
inferred remote host.
* fix(source-control): align dirty+unavailable intent expectation
Local preparation (stage/commit changes) is safe without review-lookup authority; remote actions stay blocked. Prevents dirty trees from dead-ending at sync-first when lookup is unavailable.
* fix(source-control): distinguish loading state from unavailable lookup
Require head branch presence in shouldAttemptCreateHostedReviewForIntent to
separate real unavailable-lookup results from loading placeholders, which
share the same outcome/reason pair but lack a branch name.
* test(activity): drive portal readiness latch release with explicit rAF
Wall-clock setTimeout waits for requestAnimationFrame were flaky under
CI load (shard 15/16), leaving status stuck at loading instead of ready.
* Distinguish expected absence from git errors in remote removal
Why: swallowing all errors silently masks genuine git failures.
Check presence explicitly instead, so setup/teardown can still
skip when origin is absent while letting real errors surface.
